Is there a quick way to extract descriptive statistics from a data table?

I need the mean and SD for 203 items. Is there a way I can get them quick via JMP? Thank you!

Cols> Column Viewer

To add to @David_Burnham's answer, you can very quickly get these results into a data table by right-clicking on the table in the report and selecting "Make into Data Table"

Thank you, David and Cameron! Never used the Column Viewer function before--it is fantastic! Actually right after I posted the question, I realized that Excel could have done it quick and easy, so I just did it in excel; next time I will know how to do it in JMP.

Follow up question: is there a way to add skew and kurtosis to the summary statistics in Column Viewer? I know how to do it in distribution. Thank you!

hi @xiaoyaj0,

You won't get skewness and kurtosis from Column Viewer, but you can actually do essentially the same thing I suggested for the Column Viewer in Distribution (I should have pointed this out in my first reply, lol). Right click in the summary statistics table and select "Make Combined Data Table". You will get a table with summary statistics for each column you have plotted in Distribution. At first, it will be in a long format like the screenshot below:

It's probably better to have this in a wide format, so I would recommend splitting Column 2, split by Column 1, and grouped by Y.

Your final table will look something like this:

WOW, this just blew my mind. I just tried and it totally worked. I have been using JMP for almost three years, but never knew these functions! Now I feel like I am ready to fly!

Since you have been so SUPER, I have another nagging question that you might be able to help me: when I imputate a dataset, the new imputated table never has the original group with them (in this case, it is "Level"). In another word, only the numbers show in the imputated table. Is there a way to get the words to come as well? Now I just go back to the original table and copy that column. I wonder if there is a setting to adjust that.

What version of JMP are you using? You shouldn't be getting a new data table output with Multivariate SVD or Multivariate Normal Imputation.

JMP Pro 13

I should have also asked how you are doing your imputation - what method are you using? Not that it should be any different, but I see you are also using a Mac. When I do either multivariate normal or multivariate SVD imputation on my Windows machine my original table is updated with the imputed values, no new table is created.

So i go to Analyze-Multivariate Method-Multivariate-Imputate. Thanks for helping, Bill!
